In Peru, one of the main problems to promote the development of many remote and poor localities is not having asphalt roads since in most soils they do not have the adequate mechanical properties of the subgrade. In the present thesis it is the improvement of the Pilluana - Paraíso highway, which has investigated the effect on the physical-mechanical properties of the soil with two chemical stabilizers most used by different companies in the field of road construction. The additives to be studied are PROES and CONAID, produced by the companies PROES PERU SAC and TDM Grupo, respectively. These products are stabilizers based on sulphated oils, which is their main property to increase the resistance of clay soils. Stabilizers are chemical components that help to improve the resistance properties of the soil, as a proposal for the improvement of the subgrade of the road in question, Comparisons of natural soil and improved soil were made from the results of the CBR test, using data collected from research carried out. The objective of this research is to determine the effect of the application of these additives through their dosages given in their technical sheet to improve the bearing capacity (CBR) of the subgrade of the Pilluana - Paraíso highway. Likewise, compare them to determine which of the two presents a greater increase in the mechanical properties of the soil. For the samples obtained, pits were made along the unpaved road, physical and mechanical tests were carried out for the natural soil, in the soil with the liquid additives (PROES and CONAID) and in the soil with the solid additives (PROES + CEMENTO and CONAID + CEMENTO). All tests were carried out in the particular Soil Mechanics Laboratory, based on Peruvian technical standards. Our results show that the soil is silty - clayey, according to the SUCS and AASHTO classification. On the other hand, the maximum CBR percentage for the natural soil was 3%, which, according to the MTC, is an inadequate subgrade. In the case of soil modified with PROES and CONAID liquid additives, the maximum CBR percentage is 13% and 10%, which corresponds to a good subgrade. Finally, for the solid additives PROES and CONAID, the maximum CBR percentage is 70% and 58%, which corresponds to an excellent subgrade, it is concluded that both solid additives PROES and CONAID improve the mechanical properties, which taking into account that the CONAID additive was used because less dosage was applied and it is cheaper to stabilize the soils of the Pilluana - Paraiso highway, Picota province, San Martín.
